WCFA'23 - FKM Guideline Non-Linear

Programme of the Workshop

The course is built in such a way, that no prior knowledge on fatigue analysis is needed. The basic principles of the common fatigue damage estimation are described in the first day, while the lectures on vibration fatigue analysis follow in next two days. In order to better suit the needs of participants and to fit the course to the level of their knowledge, several variants of the course are provided as shown in the table below.
